Re: Semi-Annual Effluent and Environmental Monitoring Report fromJuly to December, 2005

Dear Mr. Whitten:

In compliance with our Nuclear Regulatory Commission Radioactive MaterialLicense No. SUA-1475, Amendment No. 34, Condition 12 and 30; the attached Effluentand Environmental Monitoring Report is described and presented as listed below. Theapplicable and available data will specify the concentration of each principle radionuclidereleased to unrestricted areas in water effluent during the period of July 01, 2005 throughDecember 31, 2005. The data is also reported on the format required in regulatory Guide4.14.

Available monitoring data in this report are in order as listed below:

> Environmental Inspection Report (continued this procedure to showand maintain the integrity of the restricted tailings area.)

> Ground Water Result (available data on GW-3 Well).

> Sample Location

Presently, our environmental monitoring program is limited and the abovereported items are solely based on available data only. The required radiation monitoringand protection program will be under an RWP (Radiation Work Permit) and no RWP wasissued during this semi-annual period.

Additionally, our active radiation monitoring instruments are routinely calibratedand the personnel radiation monitoring and protection program under RWP is still ineffect but in standby status awaiting the final pond closure reclamation activity.

Sincerely,

Max Chischilly, Jr.Radiation Safety Officer-UNC
